The Jack-Knife Alert tracks the position of the trailer in relation to the vehicle and displays an alert if there is a potential jack-knife situation. The Rear Trailer View now includes guidelines when in reverse to help back into tight spots, this does require the GM auxiliary accessory camera. The Rear Side View now shows a split view of the left and right sides of the truck making it easier to to see any surrounding objects.
